IMPROVEMENT IN SASH-HOLIDERS.

The Schedule' referred to in these Letters Patent and making part of the same.

To all whom it ma/y concern.:

Be it known that I, WILLIAM A. DEVON, of Port Richmond, in the county of Richmond, and in the State of New York, have invented certain new and useful Improvements in Window-Sash Fastening; and do hereby deciare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and the letters of reference marked thereon.

In the annexed drawings, making a part of this specification- A representsya window-frame, and

B, the sasl1,`1nade to t therein.

The frame A is provided'with la suitable'reeess, in which is pivoted the catch or lock C, by means of the adjustable pin g.

D represents a metallic plate, provided with a slot, for the lock or catch C toworl; in, and is screwed to the inside of the frame A, over the recess therein.

The back side of the catch O is'provided with a cir-f cular or'curred recess, as shown, in which works the cam K, and looks or fastens said catch with the sash, either way that may be desired.

The cam K is provided with a square hole through it, through which the shaft or bolt h passes, and there by operated as may be desired.

The sash B is provided with a series of notches,x:rf, in which the upper end of the lock C catches, so as to adj ust the same at any desired elevation, and with one notch, a, made so the lower end of said lock G willl catch therein, to hold said sash down, when it may be desired to lock the same.

A small spring, j, is adjusted, as shown, throughout the upper end ofthe look C at all times when the cam K is not used.

By means of the cam K, the lower end of the lock C is forced ont, so as to, catch in the notch x', and thereby lock the sash, whenever the saine maybe required.

Having thus fully described my invention,

What I claiin as new, and desire to secure by Letters Patent, is

The oblong metal catch O, pivoted, near its centre, within the flame A, and provided with a curved recess, within which works the Cain K, to operate upon the sash B, whereby the sash is held .up or 'locked down, all constructed substantially'a's specified.

In testi inony that I claim the foregoing, I have hereunto set my hand, this 3d day of March, 1868.

WM. A. DEVON.
